Synthesis of free-standing two-dimensional (2D) conjugated covalent organic framework (COF) films linked by C?C bonds is highly desirable. Now a very simple and mild strategy has been developed to synthesize them by Suzuki polymerization on a water–toluen

Paragraph 0049-0051, (2021/06/13)
The invention discloses a synthesis method of a tetra (4-aminophenyl) porphyrin metal complex. The method comprises the following steps: 1) taking organic acid as a solvent and pyrrole and 4-halogen benzaldehyde as substrates, and carrying out condensation reaction to obtain a (4-halogen phenyl) porphyrin solid; 2) dissolving the (4-halogen phenyl) porphyrin solid in an organic solvent, adding a metal salt, and reacting to obtain a (4-halogen phenyl) porphyrin metal complex; and 3) taking the (4-halophenyl) porphyrin metal complex and ammonia water as substrates, and carrying out carbon-nitrogen coupling reaction in the presence of a catalyst and an organic solvent to obtain the tetra (4-aminophenyl) porphyrin metal complex. The method is mild in reaction condition, low in toxicity, green and environment-friendly.
UV–visible and fluorescence spectroscopic assessment of meso?tetrakis?(4?halophenyl) porphyrin; H2TXPP (X = F, Cl, Br, I) in THF and THF-water system: Effect of pH and aggregation behaviour

The current study determines optical and fluorescence response of halogen substituted series of meso?tetrakis?(4?halophenyl) porphyrin; H2TXPP (Halo = F, Cl, Br, I) dye in tetrahydrofuran; THF and THF-water system at changing pH in relationship with changing medium of allure. Effects produced by varying the pH and medium, over spectral and aggregation were discussed in detail. Results show sequential protonation and deprotonation of H2TXPP series in acidic (pH = 4) and (pH =10) basic medium. Specific structural changes of monomeric absorption band were put in evidence on lowering pH, which includes broadening and splitting of soret or B band. Other changes include increasing in intensity and red-shifting of Q1 band indicating some degree of aggregation. The side-by-side aggregation and formation of J-aggregate were quite evident. The red shift of B band featured self-aggregation through head-to-tail molecular ordering which is consonant with absorption-emission data.
