The present invention provides an N1-2-thiophen-2-ylethyl-N2-substituted biguanide derivative of formula (I) or a pharmaceutically acceptable salt thereof, a method for preparing same, and a pharmaceutical composition comprising same as an active ingredient. The inventive N1-2-thiophen-2-ylethyl-N2-substituted biguanide derivative exhibits improved blood glucose level- and lipid level-lowering effects even with a reduced dosage as compared to conventional drugs, and thus, it is useful for preventing or treating diabetes, metabolic syndromes such as insulin-independent diabetes, obesity and atherosclerosis, or a P53 gene defect-related cancer.

Three donor-acceptor, π-conjugated (D-π-A) dyes containing methylthiophene or vinylene methylthiophene as π-conjugated spacer were utilised in dye-sensitized nanocrystalline TiO2 solar cells. The relationship between the structure of the dyes and their photophysical, electrochemical and photovoltaic properties was investigated systematically. The vinyl unit, introduced as the π-conjugated spacer, leads to unfavorable back-electron transfer and decrease of the open-circuit voltage. A dye-sensitized solar cell based on 2-cyano-3-(5-(4-(diphenylamino)phenyl)-4-methylthiophenyl-2-yl) acrylic acid displayed the most efficient solar-to-electricity conversion efficiency of the dyes with a maximum η value of 8.27% (Voc?=?0.72?V, Jsc?=?15.76?mA?cm-2, FF?=?0.73) under simulated AM 1.5 G solar irradiation (100?mW?cm-2).

2,3-Dihydro-2,3-bis-(methylene)thiophene and its benzo derivate, generated flash-pyrolytically, polymerise or are trapped with HCl and PhSH but only the latter gives Diels-Alder adducts; electrocyclisation of the 3-phenylmethylene derivate is accompained by skeletal rearrangement to give naphthothiophene.
