Design and catalytic performance of a novel 2D copper MOF for green synthesis of tetrahydrobenzo[b]pyrans

Abstract This study explores the development and use of a novel 2D MOF as a heterogeneous catalyst in organic synthesis. The phosphonocarboxylic acid m-PO3CH2C6H4CO2H (L) has been employed in the synthesis of a metal carboxyarylphosphonate. The 2D MOF [Cu(H2O)(m-PO3CH2C6H4CO2H)]n (1) was synthesized in both crystal (1) and nanostructure (1 ...

Synthesis and photochromic properties of tri- and tetra-aryl-3H-naphtho[2,1-b]pyrans

, 2011
The objective of this study was to investigate the influence of 6-aryl-, 5-aryl- and 5,6-diaryl- substituents upon the photochromic properties [A-max and fading kinetics (tv,)] of 3,3-diaryl-3H- naphtho[2,1-b]pyrans.
