Electronically based indices (PDI, ATI and FLU) have been employed to investigate the substituent effect on the ¿-electron delocalization in both heterocycle and benzenoid rings. Three typical substituents (Cl, OCH3 and CN) with different inductive and resonance effect have been selected. Generally, substituent causes a reduction in aromaticity irrespective of whether it is electron attracting or electron donating. Moreover, it is found that the substituent situation with respect to the heteroatom has a significant influence on the aromaticity, and irrespective of whether the two substituents form a meta or para isomer, they preferably choose the position which leads to the maximum aromaticity character. Also, influence of increasing the number of N as heteroatom and their sequences on ¿-electron delocalization of aza derivatives of naphthalene and indole have been investigated by use of different quantitative descriptors including HOMA,NICS and electronic indices.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659300448\"\u003e\u003ch3\u003eIn Heterocyclic Analogs of Naphthalene and Indole\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659300448","offer_id":39486493524061,"sku":"9783659300448","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/d1484b45-3731-44e5-9a59-e38becdfacc4.jpg?v=1769666518","url":"https:\/\/shop.autorenwelt.de\/products\/quantitative-study-on-local-aromaticity-von-mozhgan-shahamirian","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
