It was recently reported that, besides UV irradiated polymerization, polymerization of diacetylene compounds could also been initiated by radicals generated from enzyme catalyzed hydrogen peroxide (H2O2) decomposition. A new optical

A new diphenylnaphthalene-based diamidine (1) having an N-ethyl-substituent to improve its solubility has been designed and synthesized for the recognition of dicarboxylic acids. The diamidine 1 forms 1:1 complexes with the α,ω-dicarboxylic acids in the competing protic solvent, MeOH, using the charge-assisted hydrogen bonding (i.e., formation of amidinium-carboxylate), and the formation of the complexes was determined by 1H NMR and DOSY NMR spectroscopies in a high concentration (2.0 mM). However, at a low concentration (25 μM), the turn-on fluorescence detection of the dicarboxylic acids was not successful because the diamidine 1 emits in MeOH before recognizing the carboxylic acids. Interestingly, the diamidine 1 does not emit in 2-propanaol before recognizing the α,ω-dicarboxylic acids, and succeeded in the detection of a dicarboxylic acid (turn-on response) in the protic solvent, 2-propanol. The interesting tight binding of the diamidine 1 with α,ω-dicarboxylic acids was observed in 2-propanol-d8 using 1H NMR and the restriction of the rotation of the phenyl rings of the 1,8- diphenylnaphthalene unit was also observed. These fluorescence and binding characteristics of the N-ethyl-substituted diamidine 1 are applicable for the detection of carboxylic acids in a protic solvent.

A succinimide containing phenylo boric acid functional polyurethane and its preparation method, the raw material is used for the 4 [...]carboxyl group benzene boric acid and its ortho, meta or para-derivatives, the first β alanine substitution reaction to produce amide, DCC activated carboxyl group for, and N-hydroxysuccinimide esterification reaction, to obtain corresponding succinimide ester. Its structural formula is: In the formula: R is H, X (X is F, Cl, Br, I) or NO 2. The advantage of this invention is to: high efficiency, the use of mild conditions, can be used for physiological conditions or under large biological molecule of the modification of the biological interface. Using this method, the pH response of the phenylboronic acid, sugar response introduced into the biological system. (by machine translation)
