Dynamic control over molecular emission, especially in a time-dependent manner, holds great promise for the development of smart luminescent materials. Here we report series dynamic multicolor fluorescent systems based on time-encoded locking and unlocking individual vibrational emissive units. The intramolecular cyclization reaction driven by adding chemical fuel acts as lock to decrease conformational freedom units, thus varying fluorescence wavelength, while resulting chemically locked state can be automatically unlocked hydrolysis with water molecules. system fuels multiple times. emission wavelength lifetime states readily controlled elaborating structures, indicating this strategy robust versatile way modulate multi-color manner.

Instant visualization of latent fingerprints is developed by using a series water-soluble terpyridine zinc complexes as aggregation-induced emission probes in pure water, under UV light or ambient sunlight. By simply soaking, spraying with an aqueous solution the probe, bright yellow fluorescence images high contrast and resolution are readily on various surfaces including tinfoil, glass, paper, steel, leather, ceramic tile. Remarkably, can be visualized within seconds details whorl sweat pores. The color tuned from blue to orange modifying pincer ligands, allowing direct imaging These inexpensive, water-resistant, color-tunable provide practical approach for recording analysis, security protection, well criminal investigation different scenarios.

Excess consumption of antibiotics leads to antibiotic resistance that hinders the control and cure microbial diseases. Therefore, it is crucial monitor levels in environment. In this proposed research work, an optical nano-sensor was devised can sense ultra-low concentration antibiotics, samples like tap water using fluorescent zinc oxide quantum dots (ZnO QDs) based nano-sensor. For this, different polymers (polyvinylalcohol–PVA polyvinylpyrrolidine–PVP) capped florescent ZnO QDs were synthesized a modified sol–gel technique. These used as probes presence antibiotics. The characterizations performed UV–visible absorption fluorescence spectroscopic methods while structural characteristics analyzed by Raman spectroscopy X-ray diffraction spectroscopy. formation confirmed Fourier transform infrared (FTIR). Charge on obtained with help ZETA potential. Here ten checked, Ciprofloxacin Moxifloxacin have shown excellent sensing specificity PVA-ZnO PVP-ZnO LOD 1.4 nM 0.8 nM, sensitivity 36.17 units/mM 19.33 respectively. This study also inferred tuning properties towards be achieved capping polymers.

Developing photoresponsive circularly polarized luminescence (CPL) materials is an essential step for biosensing and biomedical applications. However, fabricating CPL assemblies rooted in the chirality amplification transmission of molecular building blocks, which simultaneously show photo-controllable signals, remains challenging. Herein, a block containing overcrowded-alkene core bis-PBI (MPBI) was designed. Importantly, enantiopure MPBI can self-assemble into well-organized nanofibers via π-π stacking interactions enable intrinsic chirality, providing opposite signals. The photoisomerization induced transformation from to discrete nanospheres, accompanied by gradually decreased signal. results demonstrated development assembly chiral MPBI, provides alternatively facile strategy fabricate CPL-active would offer opportunities future
