A chiral ZnII porphyrin derivative 1 and its achiral analogue 2 were studied in the solid state. Considering the rich molecular recognition of designed metalloporphyrins 1 and 2 and their tendency to crystallize, they were recrystallized from two solvent mixtures (CH2Cl2/CH3OH and CH2Cl2/hexane). As a result, four different crystalline arrangements (1 a,b and 2 a,b, from 0D to 2D) were obtained. Solid‐state
固态研究了手性Zn II卟啉衍生物1及其非手性类似物2。考虑到设计的金属卟啉1和2的分子识别能力强,并且易于结晶,因此将它们从两种溶剂混合物(CH 2 Cl 2 / CH 3 OH和CH 2 Cl 2 /己烷)中重结晶。结果,四个不同的晶体排列(1a,b和2a,b,从0D到2D)。对所有物种进行了固态研究,以分析手性,溶剂混合物和表面(云母和HOPG)在超分子排列中的作用。通过溶剂和底物的组合,获得了各种微尺寸的物种,从囊泡到花形阵列,包括几何微晶。总体而言,结果强调了金属卟啉在环境中的敏感性以及在设计时必须考虑到这一特征。
