| Abstract | A series of new porous aromatic frameworks (PAA-VTMS) co-cured by diethynylbenzene (DEB) and vinyltrimethoxysilane (VTMS) have been described. Thermally treated PAA-VTMS were also investigated. When the ratio of DEB to VTMS was 1:1 (PAA-VTMS-4), it showed characteristic pores with uniform diameter, confirmed by scanning electron microscope (SEM) and transmission electron microscopy (TEM) analyses. The surface area of PAA-VTMS-4 was up to 457 m$^{2}$/g and its pore size was 7 nm, related to the hyper-cross-linked structure with plentiful benzene units. The co-cured PAA-VTMS samples whose DEB/VTMS ratios were higher or less than 1:1 showed low surface area. CO$_{2}$ uptake of PAA-VTMS-4 was 83 cm$^{3}$/g at 0 °C and 72 cm$^{3}$/g at 25 °C. The temperature of 5% weight loss of PAA-VTMS-4 was 388 °C in nitrogen and 346 °C in air. The surface area of the thermally treated sample (OPAA-VTMS-4) was decreased, but its CO$_{2}$ uptake was as high as 115 cm$^{3}$/g at 0 °C and 105 cm$^{3}$/g at 25 °C. The OPAA-VTMS-4 sample almost did not decompose in N$_{2}$, and the temperature of its 5% weight loss was 450 °C in air. It showed that PAA-VTMS with its new porous aromatic framework can be used at high temperature. |

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.
