The pivotal objective of this dissertation is to design and construct novel fluorescent switchable mechanically interlocked molecular architectures with symmetric stopper and to study their molecular shuttling process under acid-base stimuli control along with their controllable high contrast fluorescence and impressively selective detection of anionic guest species. In the introduction of this doctoral thesis we have described brief early synthetic attempts to create mechanically interlocked molecules (MIMs) such as rotaxanes and catenanes as well as several chemosensing mechanism and aggregation induced emission (AIE). Moreover novel templating methodologies to build MIMs and some latest examples of fluorescence MIMs based molecular shuttles under different control stimuli were also introduced. Indeed, acid-based stimuli can drive the molecular shuttling between the two stations accompanied by changing the AIE behavior of AIE-active mechanically interlocked molecule investigated. Fairly, underplayed chemo sensing mechanisms in these systems were presented. Meanwhile, we have developed facile ratiometric sequential detection of copper and pyrophosphate based on rhodamine appended derivatives in this doctoral thesis as well. In chapter two, a novel multifunctional mechanically interlocked switchable [2]rotaxane R4 containing two molecular stations and rotaxane arms terminated with boron-dipyrromethene (BODIPY) fluorophores and its derivatives were synthesized for the first time by CuAAC click reaction. The shuttling motion of macrocycle between the dibenzylammonium and triazolium recognition sites and the distance dependent photoinduced electron transfer process of R4 is demonstrated by utilizing external chemical stimuli (acid/base). Interestingly, the reversible self-assembly process of R4 was recognized by the acid–base molecular switch strategy. Notably, two symmetrical triazolium groups acted as molecular stations, H2PO4– receptors, and H-bonded donors. Both [2]rotaxane R4 and thread R2 demonstrated excellent optical responses and high selectivity toward H2PO4– ion. The specific motion and guest–host interactions of mechanically interlocked machines (MIMs) were also further explored by quantum mechanical calculations. The thread R2 also demonstrated to enable the detection of H2PO4– in RAW 264.7 cells successfully. In chapter three, a novel near IR fluorescent switchable [2]rotaxane NIR4 composed of two different molecular stations and rotaxane arms terminated with near IR boron-dipyrromethene (BODIPY) fluorophores and its derivatives were synthesized for the first time by CuAAC click chemistry. The molecular shuttling motion could be addressed by the fluorescence signal transduction via distance dependent photo-induced electron transfer process of [2]rotaxane NIR4 triggered by external chemical stimuli (acid/base). The construction and efficient synthesis of [2]rotaxane NIR4 with high level of structural complexity designed always more challenging task of selective anion sensing. Conspicuously, the key to design involved encoding the flexible arms of [2]rotaxane NIR4 triazolium moiety acted as molecular stations and H-bonded donors, which exhibits impressive selectivity and sensitivity toward complementary anionic gust species. The specific mechanical molecular motion of [2]rotaxane NIR4, host-guest interactions of NIR2 and mechanically interlocked molecules (MIMs) were also further explored by quantum mechanical calculations. Importantly, the host of NIR2 and [2]rotaxane NIR4 could be applied for the vivo imaging and clarify the distribution of H2PO4- at subcellular levels. In chapter four, a novel AIE-active switchable [2]rotaxane TR2 incorporating two different molecular stations and rotaxane arms terminated with AIE-active TPE fluorophores and its derivatives were synthesized for the first time by click chemistry. The shuttling behavior of macrocycle component between the two molecular stations can be driven by external acid-base stimuli in solution, accompanied by NMR spectral changes. Investigation of their AIE fluorescence behavior changes showed that these analogous rotaxane are controlled by the molecular motion of the macrocycle component in the presence of external acid-base stimuli. The anion-templated construction of [2]rotaxane TR2 with high level of structural complexity designed always more challenging task. Evidently, the key to design involved encoding the flexible arms of both triazolium motif, is described which exhibit impressive selectivity and sensitivity toward complementary anionic gust species. The specific mechanical molecular motion and host-guest interactions of mechanically interlocked machines (MIMs) were also further explored by quantum mechanical calculations. Importantly, the AIE- active behaviors of [2]rotaxanes TR1, TR2 and TR3 were further investigated to study their potential bio-imaging application and specifically [2]rotaxane TR2 could be applied in vivo imaging with H2PO4- at subcellular levels. In chapter five, two rhodamine hydrazine derivatives Rh1 and Rh2 with catechol and ether functionalities have been synthesized and utilized towards sequential colorimetric detections of Cu(II) and pyrophosphate (PPi) ions in CH3CN–H2O (v/v = 9 : 1, 5 mM Tris–HCl, pH 7.4) semi-aqueous medium. Notably, Rh1 and Rh2 are the first example of colorimetric rhodamine-based probes for the sequential detections of Cu2+ ion and PPi anion. Based on the significant colorimetric responses (from colorless to pink) of Rh1 and Rh2 to Cu2+ ions, the detection limits were estimated as low as 1.22 × 10−8 M and 8.0 × 10−7 M, respectively, which signified the utilities of designed probes towards facile detections of Cu2+ ions. Furthermore, upon the successive addition of PPi ion to Rh1–Cu2+ and Rh2–Cu2+complexes, it has been altered and restored to its origin of Rh1 and Rh2 via re-coordination of PPi to Cu2+ ion, which was confirmed by color changes from pink to colorless. Moreover, computational DFT calculations provided more insights into HOMO–LUMO structures of rhodamine derivatives and their copper complexes. Additionally, the solid state strip-based colorimetric detections of Cu2+ ion were supplemented as a real time application. Thus in conclusion, novel fluorescence mechanically interlocked molecules designed to act as molecular switches have proceeded apace. Delightfully, the molecular shuttling to achieve by the addition of acid-base and studied on AIE behavior indicate that the molecular motion of macrocycle component could induce change the aggregation state of the AIE-active mechanically interlocked molecule. The remarkable stimulated responses towards dihydrogen phosphate (H2PO4-) were discussed. Furthermore, sequential detection of copper and pyrophosphate via ratiometric sensor based on rhodamine derivatives were presented in detail.
