| Abstract | Three isoreticular metal–organic frameworks, JUC-100, JUC-103 and JUC-106, were synthesized by connecting six-node dendritic ligands to a $[Zn_{4}O(CO_{2})_{6}]$ cluster. JUC-103 and JUC-106 have additional methyl and ethyl groups, respectively, in the pores with respect to JUC-100. The uptake measurements of the three MOFs for $CH_{4},$ $C_{2}H_{4},$ $C_{2}H_{6}$ and $C_{3}H_{8}$ were carried out. At 298 K, 1 atm, JUC-103 has relatively high $CH_{4}$ uptake, but JUC-100 is the best at 273 K, 1 atm. JUC-100 and JUC-103 have similar $C_{2}H_{4}$ absorption ability. In addition, JUC-100 has the best absorption capacity for $C_{2}H_{6}$ and $C_{3}H_{8}.$ These results suggest that high surface area and appropriate pore size are important factors for gas uptake. Furthermore, ideal adsorbed solution theory (IAST) analyses show that all three MOFs have good $C_{3}H_{8}/CH_{4}$ and $C_{2}H_{6}/CH_{4}$ selectivities for an equimolar quaternary $CH_{4}/C_{2}H_{4}/C_{2}H_{6}/C_{3}H_{8}$ gas mixture maintained at isothermal conditions at 298 K, and JUC-106 has the best $C_{2}H_{6}/CH_{4}$ selectivity. The breakthrough simulations indicate that all three MOFs have good capability for separating C2 hydrocarbons from C3 hydrocarbons. The pulse chromatographic simulations also indicate that all three MOFs are able to separate $CH_{4}/C_{2}H_{4}/C_{2}H_{6}/C_{3}H_{8}$ mixture into three different fractions of C1, C2 and C3 hydrocarbons. |

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.
