Three kinds of π-conjugated perylenetetracarboxylic diimide (PTCDI)-based organic functional derivatives, i.e., N,N'-di(2-ethylhexyl)-3,4,9,10-perylene diimide (molecule 1), N,N'-di(2-ethylhexyl)-1,7-dithien-2-yl-3,4,9,10-perylene diimide (molecule 2), N,N'-di(2-ethylhexyl)-1,7-di(2-bromothien-5-yl)-perylene-3,4,9,10-perylene diimide (molecule 3), have been(More)
In the title complex, [Na(C(2)HCl(2)O(3)S(2))(C(10)H(20)O(5))], there are two independent complex units in the asymmetric unit, one of which has a 55:45% disorder in the 15-crown-5 component. The coordination sphere about the Na atom in each complex unit comprises five bonds to O atoms of the crown ether [Na-O = 2.390 (7)-2.466 (6) Å] and one to a(More)
OBJECTIVE To explore influential factors of local therapeutic effect in CT guided brachytherapy of (125)I seeds for non-small-cell lung carcinoma (NSCLC). METHODS Totally 141 primary NSCLC patients diagnosed by bronchoscope or puncture biopsy were treated with CT guided (125)I seeds implantation treatment from 2003 January to 2005 January. Among them, 26(More)
In the macrocyclic title compound, C(26)H(12)Cl(2)N(6)O(4), an O-atom-bridged calix[2]naphthalene-[2]triazine synthesized using a one-pot approach from naphthalene-2,7-diol and cyanuric chloride, the two isolated naphthalene planes and the two triazine-2,6-di-oxy planes adopt a 1,3-alternate configuration, with a dihedral angle of 84.10 (8)° between the(More)
In the title compound, C(21)H(20)Br(2)O(2)S, prepared by the reaction of 1,9-bis-(4-bromo-phen-yl)nona-2,7-diene-1,9-dione with sodium sulfide nona-hydrate in acetonitrile, the six-membered thio-pyran ring has a chair conformation while the H atoms ortho to the S atom adopt a cis configuration. The dihedral angle between the two benzene rings is 2.59 (8)°.
Many experimental factors and uncontrollable factors may introduce errors in the distance measurement by continuous wave electron paramagnetic resonance. To deal with this problem, several C60 nitroxide diradical adducts with rigid structure and definite molecular dimension were used as distance calibration rulers. Based on the improvement of distance(More)
