The main result of this article presents the closed formula of neighborhood M-polynomial of oligothiophene dendrimer which is used for computing the neighborhood topological indices of the dendrimer. Among the various indices considered, the forgotten index obtained the highest value, followed by the Sanskruti index, first Zagreb index, and second Zagreb index. These topological indices exhibited an increasing trend as the number of generation increases across the dendrimer structure. Conversely, the general Randic index, harmonic index, geometric-arithmetic index and atom bond connectivity index are the least dominant indices, they display minimal increase as the generation increases. The significance of adopting the neighborhood M-polynomial to compute the topological index lies in the fact that it facilitates the analysis of complex molecules in a timely manner and allows pendant vertex to contribute more effectively to the overall degree value of the dendrimer. Furthermore, the dataset resulting from these topological indices serves as a foundation for future studies aimed at predicting the physicochemical properties of the dendrimer.<\/jats:p>","DOI":"10.1051\/ro\/2024138","type":"journal-article","created":{"date-parts":[[2024,7,2]],"date-time":"2024-07-02T18:59:47Z","timestamp":1719946787000},"page":"149-161","source":"Crossref","is-referenced-by-count":4,"title":["Exploring topological indices of oligothiophene dendrimer <i>via<\/i> neighborhood M-polynomials"],"prefix":"10.1051","volume":"59","author":[{"given":"Muhammad Shafii","family":"Abubakar","sequence":"first","affiliation":[]},{"given":"Kazeem Olalekan","family":"Aremu","sequence":"additional","affiliation":[]},{"given":"Maggie","family":"Aphane","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2607-4847","authenticated-orcid":false,"given":"Muhammad Kamran","family":"Siddiqui","sequence":"additional","affiliation":[]}],"member":"250","published-online":{"date-parts":[[2025,1,16]]},"reference":[{"key":"R1","doi-asserted-by":"crossref","first-page":"487","DOI":"10.3390\/axioms11090487","volume":"11","author":"Abubakar","year":"2022","journal-title":"Axioms"},{"key":"R2","doi-asserted-by":"crossref","unstructured":"Abubakar M.S., Aremu K.O., Aphane M. and Amusa L.B., A qspr analysis of physical properties of antituberculosis drugs using neighbourhood degree-based topological indices and support vector regression.
