Electrically Conductive Photoluminescent Porphyrin Phosphonate Metal–Organic Frameworks

Herein, the design and synthesis of a highly photoluminescent electrically conductive metal–organic framework [Zn{Cu-p-H6TPPA}]⋅2 [(CH3)2NH] (designated as GTUB3), which is constructed using 5,10,15,20-tetrakis [p-phenylphosphonic acid] porphyrin (p-H8TPPA) organic linker, reported. The bandgap GTUB3 measured to be 1.45 1.48 eV diffuse reflectance spectroscopy photoluminescence (PL) spectroscopy, respectively. PL decay measurement yields charge carrier lifetime 40.6 ns. Impedance DC measurements yield average electrical conductivities 0.03 4 S m−1, respectively, making rare example an 3D framework. Thermogravimetric analysis reveals that components are stable up 400 °C. Finally, its specific surface area pore volume calculated 622 m2 g−1 0.43 cm3 g−1, grand canonical Monte Carlo. Owing porosity high conductivity, may used low-cost electrode material in next generation supercapacitors, while low make it promising for optoelectronic applications.
