در این پروژه، روش کلی سنتز دو سری از کمپلکس های سیکلومتاله شده ارگانو پلاتین که شامل لیگاند های 2-فنیل پیریدین (h-ppy) و benzo[h]quinolone می باشد ارائه شده است که از واکنش 2 اکی مولار از لیگاند های benzo[h]quinoline (bhq) وc^n= 2-phenylpyridine (ppy) در استون با دایمر cis,cis-[pt2me4(µ-sme2)2]، کمپلکس های [pt(ppy)(sme2)me]، 1 و [pt(bhq)(sme2)me]، 2 را می دهد. زمانی که کمپلکس های 1 و 2 با 1 اکی...
teachers beliefs have usually been left unattended in the realm of educational research in iranian context. one of those beliefs which seems to impact teachers performance in the classroom is their sense of self-efficacy, which refers to teachers belief in their ability to enhance student achievement and in bringing about positive learning outcomes. the present study aimed to investigate the pr...
We studied the second-order NLO properties in solution of various Ir(III) acetylacetonate complexes bearing a substituted cyclometallated 4-styryl-2-phenylpyridine (ppy-4-styryl-R, with R = NEt2, OMe, H, NO2) with the EFISH technique. The dipole moments were evaluated by Density Functional Theory (DFT) calculations. We have also investigated the Second Harmonic Generation (SHG) of composite fil...
this study describes the organic synthesis of 5-(2-amimo-4-styryl pyrimidine-4-yl)-4-methoxy benzofuran-6-ol (spbf) as an example of a benzofuran derivative used as a new series of amyloid imaging agents. these benzofuran derivatives may be useful amyloid imaging agents for detecting b-amyloid plagues in the brain of alzheimer’s disease. the precursor is 1-[6-hydroxy-4-methoxybenzofuran-5-yl]-p...
Telomerase adds telomeric DNA repeats to the ends of linear chromosomal DNA. 3'-Azido-3'-deoxythymidine 5'-triphosphate (AZTTP) is a known telomerase inhibitor. To obtain more selective and potent inhibitors that can be employed as tools for studying telomerase, we investigated the telomerase-inhibitory effects of purine nucleosides bearing a 3'-down azido group: 3'-azido-2',3'-dideoxyguanosine...
