UV-triggered degradation is an efficient method for disposing of polymers that are no longer
usable or needed. Although various photolabile molecules have been employed to design …

In contrast to the conventional two‐step method, which involves the generation of reactive
functional groups followed by incubation in a dye solution (a wet developing process), the …

An asymmetric vinylogous Mannich reaction between 3‐cyano‐4‐methylcoumarins and N‐
Boc isatin imines catalysed by amide phosphonium salt is described. This method allows the …

A new polybenzoxazole containing an adjacent hydroxyphenyl group was synthesized by
using Suzuki coupling reaction accompanied by a simultaneous elimination reaction of …

Abstract Aromatic polyoxadiazole derivatives containing 9, 9′‐dioctylfluorene were
successfully synthesized via the Suzuki coupling reaction. The oxadiazole moiety in the …

A novel water‐soluble fluorescent material was prepared via ring‐opening reaction between
4‐methyl‐7‐(2, 3‐expoxypropoxy) coumarin (MEC) and poly (vinyl alcohol)(PVA). The …

The photophysical behaviour of 7-mercapto-4-methylcoumarin (C-SH) and derivatives has
been studied in different solvents. In contrast to 7-hydroxy-4-methylcoumarin, C-SH shows …

BACKGROUND: In recent years, many fluorescent chemosensors with various
macromolecular structures have been prepared for the detection of protons or metal cations …

The significant progress recently achieved in designing smart acid‐responsive materials
based on intramolecular charge transfer inspired us to utilize excited‐state intramolecular …

Bicolor fluorescent micro‐patterns in the polymer film are prepared through the use of a new
group of photobase generator containing phthalimido carbamate groups. The photobase …
