Entropy structural characterization of zeolites BCT and DFT with bond-wise scaled comparison

Abstract

Entropy of a connected network is a quantitative measure from information theory that has triggered a plethora of research domains in molecular chemistry, biological sciences and computer programming due to its inherent capacity to explore the structural characteristics of complex molecular frameworks that have low structural symmetry as well as high diversity. The analysis of the structural order is greatly simplified through the topological indices based graph entropy metrics, which are then utilized to predict the structural features of molecular frameworks. This predictability has not only revolutionized the study of zeolitic frameworks but has also given rise to new generations of frameworks. We make a comparative study of two versatile framework topologies namely zeolites BCT and DFT, which have been widely utilized to create a new generation of frameworks known as metal organic frameworks. We discuss bond-additive topological indices and compute entropy measure descriptors for zeolites BCT and DFT using degree and degree-sum parameters. In addition, we perform bond-wise scaled comparative analysis between BCT and DFT which shows that zeolite BCT has greater entropy values compared to zeolite DFT.

“…In light of its significance in numerous scientific domains, including electronics [ 64 ], organic photovoltaics [ 65 ], and optoelectronic devices [ 66 ], polycyclic aromatic hydrocarbons have become the subject of extensive experimental and theoretical research. Some of the larger polycyclic compounds are often used as a cutout and model for materials made of glassy carbon and graphite sheets [ 67 ].…”

Comparative analysis of modified reverse degree topological indices for certain carbon nanosheets using entropy measures and multi criteria decision‐making analysis

“…This innovation led to Kulli's exploration reverse degree topological indices for subsequent advancements [16]. The concept of entropy, as formulated by Shannon, quantifies the level of unpredictability or uncertainty in the information contained within a datasets [17,18]. Entropy is a measure of the number of possible microstates (different arrangements of atoms and molecules) that a system can be in.…”
