- Metal-free, visible-light photoredox catalysis: Transformation of arylmethyl bromides to alcohols and aldehydes
-
A mild, simple, and controllable metal-free photocatalytic system for the transformation of arylmethyl bromides to corresponding alcohols and aldehydes in high yields with visible-light irradiation has been achieved. Eosin Y was found to be an efficient promoter for this oxidative dehalogenation reaction under photo irradiation conditions.

- Effect of the bridge substitution on the efficiency of dye-sensitized solar cells
-
We have designed and synthesized a novel D-π-A dye based on zinc porphyrin as the donor, cyanoacrylic acid as the acceptor and trans-bis(3,4-ethylenedioxythiophene)vinylene as the bridge. Under standard global AM 1.5 solar conditions, the Zn-porphyrin-2-EDOT sensitizer based cell gave a JSC of 7.28 mA cm-2, VOC of 0.438 V was obtained with a FF of 0.514, corresponding to an overall conversion efficiency η = 1.64%. The reasons for this low efficiency are analyzed to try to develop knowledge for future dye designing.

- Phenyl-EDOTn derivatives as super acid labile carboxylic acid protecting groups for peptide synthesis
-
A series of new 3,4-ethylenedioxy-2-thenyl (EDOTn) derived alcohols have been synthesized and evaluated as super acid labile carboxylic acid protecting groups. All the derivatives are labile to very low concentrations of TFA (0.01-0.5%).
