Autor: Suleshi Niwarthana Abeysingha, Ishanie Rangeeka Perera, R.P. Wijesundera, Champika V. Hettiarachchi
Publikováno v: Materials Chemistry and Physics. 251:123109
3D-Coordination polymers (3D-CP) consisting of zinc and fumaric acid (FMA) were synthesized under solvothermal (ZnF-Sol) and reflux (ZnF-Ref) conditions with same Zn: FMA molar ratio in DMF. The structures and the properties of the 3D-CPs were found

Metal–Organic Frameworks in Dye-Sensitized Solar Cells
Autor: Ishanie Rangeeka Perera, R. J. K. U. Ranatunga, Champika V. Hettiarachchi
Publikováno v: Energy, Environment, and Sustainability ISBN: 9789811333019
In 1991, the very first high-efficiency dye-sensitized solar cell (DSC) was reported by Brian O’Regan and Michael Gratzel. Since then these devices have been steadily developed around the world. Environment friendliness, cost-effectiveness, easy fa

Pseudo crystalline state thermochromic and reverse-photochromic reactivity of spiroindolinobenzopyran upon encapsulation into Zn-MOF-74
Autor: U. G. Randika Lakmali, Champika V. Hettiarachchi
Publikováno v: CrystEngComm. 17:8607-8611
After inclusion into the rigid channels of Zn MOF-74 crystals, molecules of spiroindolinobenzopyran (SPH) turned thermochromic by converting to its red merocyanine form on heating and reverse-photochromic by converting to its yellow spiro form under
