Temperature viscosity variation measurements demonstrated that phenyl group at 1‐position N ‐position) pyrrole core can act as rotor pyrrole‐based molecules, which consume excited energy reduce molecular solution. without effectively enhance...
Kluyveromyces marxianus is a food-grade yeast known for its diverse beneficial traits, making it an attractive candidate both food and biotechnology applications. This study explores the potential of as promising alternative protein source single-cell (SCP) production. Various strains were isolated screened from traditional fermented dairy products, with NS127 identified most strain due to superior growth characteristics, high SCP yield, environmental tolerance. Notably, demonstrated...
Five organic luminophores, 1,2,5-triphenylpyrrole (TPP) derivatives 3 a-e bearing electron-withdrawing or electron-donating groups, have been synthesized by Pd-catalyzed Suzuki coupling of 1-phenyl-2,5-di(4'-bromophenyl)pyrrole and para-substituted phenylboronic acid derivatives.

The charge distribution, molecular structure, and morphological packing significantly affect the photophysical properties of organic photoluminescent materials. In this work, two triphenylpyrrole isomers, 1,2,5- (TPP1) 1,3,4- (TPP2), were first synthesized characterized. Because their different substituent positions, TPP1 possesses aggregation-caused emission quenching (ACQ) behavior while TPP2 exhibits aggregation-induced (AIE). Their systematically investigated by using UV–vis absorption...
