| Summary: | Supramolecular organization of π-conjugated chromophores into well defined nanostructures has gained much attention due to their promising role as active components in organic electronics. Charge-transfer (CT) nanostructures, in which aromatic donor (D) and acceptor (A) molecules are alternately arranged, (mixed stack) have emerged recently as prospective candidates in this direction, because they provide inherent, uniform doping conducive for excellent conducting properties. The present perspective highlights the importance of charge transfer (CT) based non-covalent interactions, with emphasis on supramolecular design principles, for construction of various CT nano-architectures. The whole article is divided into three parts themed on the type of interactions used for obtaining CT assemblies. Through some of our recent results, we have attempted to highlight the latent potential of this nascent field. Furthermore, we have presented our perspectives on the major challenges in this field which is expected to broaden the scope of this subject.
Supramolecular design principles for construction of charge transfer based nanostructures are reviewed for various applications and future prospects are highlighted. |

| Bibliography: | Subi J. George received his PhD degree at the National Institute for Interdisciplinary Science and Technology, India in 2005 under the supervision of Dr A. Ajayaghosh. From 2005 until 2008, he had a post-doctoral stay at the Laboratory of Macromolecular and Organic Chemistry, Eindhoven University of Technology, The Netherlands, under Prof. Dr E. W. (Bert) Meijer and Dr Albert Schenning. Here his major impetus was on understanding concepts in supramolecular chirality. He is currently Assistant Professor at the New Chemistry Unit of JNCASR, Bangalore, India. His research interests focus on Functional organic and hybrid materials using molecular self-assembly. K. Venkata Rao studied MSc Chemistry at the School of chemistry, University of Hyderabad, India and obtained his MSc degree in 2008. He then subsequently joined as an R&D assistant at Supramolecular Chemistry Laboratory, New Chemistry Unit, Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bangalore, India under the supervision of Dr Subi J. George. From January 2009, he has worked as a PhD student in the same laboratory. His research work at Supramolecular Chemistry Laboratory focuses on light-harvesting soft-hybrids, conducting charge-transfer supramolecular nanowires and multifunctional porous organic polymers. Mohit Kumar obtained his MSc degree in chemistry from Sri Sathya Sai Institute of Higher Learning, Andhra Pradesh (India) in 2009. There after he joined Jawaharlal Nehru Centre for Advanced Scientific Research as a PhD student, under the guidance of Dr Subi J. George. Presently, he is a senior research fellow at the supramolecular chemistry lab. His research is mainly focussed on dynamic self-assembly of chromophores and guest induced chirality in functional supramolecular polymers.
