Designing and characterisations of small molecule environment sensitive fluorophores are extremely significant in the viewpoint of bio-chemical and bio-physical studies. These are extremely precious owing to their capability to probe micro-environments which can decipher bulk information in the study of molecular biology, drug discovery, material science, tissue diagnostics, environmental indicators, enzyme substrates, cellular staining agents, light emitting diodes, potential photosensitive biological units, fluorescent markers in biology, photo-induced electron sensors and in diverse fields of chemistry (photoelectrical dyes, supramolecular recognitions and medicinal chemistry). Although numerous fluorophores are known in the form of coumarins, fluoresceins, cyanines, oxazines, pyrenes, quinines, carbazoles, bodipy dyes etc., the quest for newer ones is still on as these are extremely essential to visualise a biochemical process.
These organic frameworks possess appropriate electronic and charge transport properties, as well as a large π-conjugated system. They are particularly beneficial for fluorescent labelling as they encompass a broad array of photophysical properties including molar absorptivity, quantum yield, stokes shift, lifetime and ability to respond towards the immediate environment.
This special issue is to improve the dissemination of advanced research in the area of ‘Development of New Synthetic Fluorophores Having Probable Biological and Environmental Significances’. Original research papers are solicited in any aspect of designing of novel fluorophores and their applications.
