Dual π-rickart modules
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 2012)
Sea R un anillo arbitrario con identidad y M un R-modulo derecho con S=EndR(M). En este artículo introducimos los módulos π-Rickart duales como una generalización de los anillos π-regulares así como también de los módulos ...
N-H...Br, Br...π and π...π interactions toward self-assembly of the cytosine hydrobromide: crystal structure, infrared spectroscopy and thermal behavior
(Elsevier BVAmsterdam, 2013-09)
The cytosine hydrobromide (CytHBr) was obtained and studied by single-crystal X-ray diffraction, FT-IR spectroscopy and thermal analysis. This salt crystallizes in the P'2IND.1/n space group with one ionic-pair CytH+Br in ...
Mechanistic study of the formation of multiblock π-conjugated metallopolymer
(2016-01-01)
Electropolymerization of a π-conjugated polymer from [N,N′-bis(salicylidene)-o-phenylenediamine]nickel(II) complex ([Ni(salophen)]) on the surface of indium-tin-oxide (ITO) was studied. Two structures of the polymer have ...
Molecular modeling of low bandgap diblock co-oligomers with π-bridges for applications in photovoltaics
(2018-09-01)
Recently, the diblock co-oligomers concept, a new design method to obtain conjugated organic compounds for varied applications in photovoltaics was proposed. These materials combines the interesting properties of extended ...
Comparison of halogen bonding and van der Waals and π-π Inter-actions in 4,5-dibromo-2-hexyl-oxyphenol
(Wiley Blackwell Publishing, Inc, 2009-04)
The title compound, C12H16BrO2, is an inter-esting case of a simple organic mol-ecule making use of five different types of intra- and inter-molecular inter-actions (viz. conventional and nonconventional hydrogen bonds, ...
A theoretical study of thionine: spin–orbit coupling and intersystem crossing
(2012-12-01)
A study of the possible intersystem crossing (ISC) mechanisms (S ⇝ T) in thionine (3,7-diamino-phenothiazin-5-ium), which is conducive to the efficient population of the triplet manifold, is presented. The radiationless ...
