Conducting complexes

The properties are very sensitive to composition and the charge carriers are apparently positive. Other studies have shown poly(acenaph-thalene) to be only slightly photo-conductive while the nitrated polymer exhibits a photocurrent dependent upon the degree of nitration (100). Since the number of mobile n electrons is the same as in poly (vinyl naphthalene), the authors conclude that some form of stereoregularity is required for enhanced conductivity. Complexes of poly(vinyl anthracene) with halogen molecules show enhanced conductivity and reduced activation energy which is thought to be typical of an electronic semiconductor (101). 

The fourth part of SMP Report addresses all main sources of real and potential hazard when conducting complex decommissioning and environmental rehabilitation activities. All complex decommissioning and environmental rehabilitation objects considered in the SMP Report have been distributed over three categories in terms of their radioecological and any other hazard (risk) for personnel, population and environment, i.e. over the following risk categories ... 

Dithiolate conducting complexes, molecular structures of 90UK-1179. 

The electronic spectrum of (14) and its isomer (20) which both form highly conductive complexes with TCNQ and analogous acceptors have been reported <90BCJ244l>. The solvatochromic behavior of the ditellurides (1), (21), and (22) has also been discussed <93JA885>. 

Temperature independent paramagnetism often observed /2 -5/ in highly conducting complexes is usually explained as being due to Pauli paramagnetism of a degenerated electron gas. In our case, however, the low conductivity values make such an explanation rather dobious. 

The heterocycles (13) and (14a) (Table 2) find much application in electrochemical polymerization to prepare electroconductive polymers <89TL1655>. The conductive complexes (239), named 2,6-bis(dicyanomethylene)-2,6-dihydrodithieno[3,2-h 2, 3 -d]thiophene, have been described as potential electron acceptors <89BCJ1547>.
