| Abstract | Summary form only given. We report recent results on modified perylene molecular conductors, derived from 1,2,7,8-tetraliydrodicyclopenta-(cd-1m)perylene (CPP) and from perylothiophene, (PeT) with the counter-ions 1/sub3/- and Ni(mnt)/sub 2/- (mnt= maleonitriledithiolate), with general formula CPP/sub 2/(13) (I/sub 3/)/sub 1-/spl delta/[1] and PeT/sub 3/[Ni(rnnt)/sub 2/]/sub 2/, respectively. Single crystals of CPP/sub 2/(I/sub 3)/sub 1-/spl delta/, appear in two different morphologies, and the crystal structures consist of regular stacks of CPP molecules and one-dirnensional disordered chains of I/sub 3//sup -/ located in channels between four CPP stacks. The different crystal morphologies exhibit different physical properties which are related to different degrees of iodine content and ordering. An important feature of these materials, when compared to the well known perylene-iodine complexes is the fact that the bulky -CH/sub 2-/H/sub 2-/ groups attached to the perylene molecular architecture interact with the triiode anions locking them in a stable composition. The transport, ESR and magnetic properties of these modified perylene molecular conductors will be reported in detail and related to the electronic and crystal structures. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
