| Abstract | We have synthesized three new salicylaldimine difluoroboron complexes with tert-butyl groups 1B–3B, which are highly emissive in solutions and in solid states. It was found that salicylaldehydehydrazone difluoroboron complex 1B could form organogels in n-hexane and the mixture of petroleum ether/CH2Cl2, and 1D nanoribbons with intense blue emission could be fabricated via the gelation of the nontraditional organogelator 1B directed by balanced π–π interaction. However, the other two salicylaldimine difluoroboron complexes 2B and 3B with a spacer of the benzene ring could not form a gel due to the strong π–π interaction, but exhibited piezofluorochromic behaviors. The as-prepared crystals of 2B and 3B giving blue-green fluorescence could be transformed into the powders emitting yellow light upon grinding, and the emission could recover when the ground powders were heated. It suggested that the reversible piezofluorochromism originated from the transformation between crystalline and amorphous states. It provided a strategy for designing new nontraditional π-gelators and piezofluorochromic materials via tuning the π–π interaction. |

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.
