properties of novel 2(1H)-pyridones. The compounds were found to be virtually non-fluorescence in solution while modestly fluorescent in solid state. The solvent effects on the UV–vis and fluorescence maxima were estimated by means of a series of ab-initio quantum chemical calculations in conjunction with Polarizable Continuum Model (PCM) method. Influence of structural displacements and intermolecular
对新型2(1 H)-吡啶酮。发现该化合物在溶液中实际上是无荧光的,而在固态中则是适度的荧光。通过一系列从头算量子化学计算,结合可极化连续体模型(PCM),估算了溶剂对UV-vis和荧光最大值的影响。通过使用碎片分子轨道(FMO)方案,对两种代表性化合物的光谱进行了详细的研究,考察了晶体结构位移和分子间相互作用的影响。光谱的FMO对相互作用分析表明,(1)分子间氢键引起红移;(2)静电相互作用引起蓝移;(3)晶体堆积效应在真空中从最大值整体上引起了蓝移。
