این رساله در دو بخش تهیه و تنظیم شده است: در بخش اول، ابتدا دو سری از کمپلکس های کبالت(iii) با دو نوع لیگاند باز شیف پنج دندانه ی مشتق شده از 2-هیدروکسی-1-نفتالدهید (که در یک گروه متیلن در بخش آمینی لیگاند تفاوت دارند) و لیگاندهای محوری مختلف سنتز شده اند: [coiii{(naph)2dien}(pprdn)]bph4 (1) [coiii{(naph)2dien}(prldn)]bph4 (2) [coiii{(naph)2dien}(py)]bph4 (3) [coiii{(naph)2dien}(n-meim)]b...
هدف اصلی این پروژه تحقیقاتی سنتز و بررسی خصوصیات دو سری از کمپلکس های باز شیف کبالت(iii) بود. برای انجام این کار، در مرحله ی اول لیگاند باز شیف بیس (پیرول-2-کربوکسی آلدهید)-3،1-دی ایمینو پروپان، bpd از طریق واکنش بین 2-پیرول کربوکسی آلدهید و 1،3-دی-ایمینو پروپان تهیه شد. در مرحله ی دوم کمپلکس coii(bpd) از واکنش بین لیگاند باز شیف و co(ch3coo)2.4h2o سنتز شد. در مرحله سوم، واکنش تحت هوادهی بین کم...
The coastal octopus at Saint Paul and Amsterdam Islands is Octopus vulgaris Cuvier 1797. Meristic and morphological characters, along with phylogenetic analysis of COI and COIII DNA sequences, were used to identify 11 animals collected in 2000 or 2001. The range of the species is therefore expanded to include the oceanic islands of the central southern Indian Ocean. The trees also depicted the ...
More than 100 mitochondrial (mt) DNA mutations have been described in association with different complex neurological disorders and with respiratory chain (RC) deficiency in the past decade. Aside from more frequently reported mt tRNA mutations and deletions, a growing list of pathogenic mutations affecting structural genes of mtDNA encoded respiratory chain subunits, mainly cytochrome b and cy...

The structural characterization of de novo designed metalloproteins together with determination of chemical reactivity can provide a detailed understanding of the relationship between protein structure and functional properties. Toward this goal, we have prepared a series of cyclic peptides that bind to water-soluble metalloporphyrins (FeIII and CoIII). Neutral and positively charged histidine-...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
A conducting molecular crystal TPP[MnIII(Pc)(CN)2]2 (MnIII: d4, S = 1, TPP = tetraphenylphosphonium and Pc = phthalocyanine) was fabricated. In its crystal structure, the [MnIII(Pc)(CN)2] units formed a one-dimensional regular chain along the c-axis with an overlap integral value of 8.6 × 10-3. TPP[MnIII(Pc)(CN)2]2 showed a semiconducting behaviour that also has been observed for isostructural ...
We demonstrate photocatalytic hydrogen evolution using COF photosensitizers with molecular proton reduction catalysts for the first time. With azine-linked N2-COF photosensitizer, chloro(pyridine)cobaloxime co-catalyst, and TEOA donor, H2 evolution rate of 782 μmol h-1 g-1 and TON of 54.4 has been obtained in a water/acetonitrile mixture. PXRD, solid-state spectroscopy, EM analysis, and quantum...
