Thermal oxidative decomposition of samples of crystalline hydrobromide and borofluoride complexes (BODIPY) of a series of 2,2′-dipyrrolylmethenes (HL) was studied by means of thermogravimetry in an atmosphere of air oxygen. An increase in the degree and symmetry of substitution, aromaticity, and the length of the substituents in 4,4′-positions of the pyrrole ligand rings increases stability of the
在空气氧气氛中,通过热重分析法研究了一系列2,2'-二吡咯基亚甲基(HL)的结晶氢溴酸盐和硼氟化物配合物(BODIPY)样品的热氧化分解。吡咯配体环的4,4′-位的取代度和对称性,芳香性和取代基的长度的增加,增加了BODIPY染料对氧化降解的稳定性。进行了结构因素对氢溴化物(HL·HBr),d-金属(ML 2)和硼(III)与2,2'-二吡咯基亚甲基配合物的热解性的影响的比较分析。
