While the facile and modular synthesis allows the fine\u2010tuning of their optical absorptions and redox properties, single\u2010crystallographic and theoretical analysis of these P\u2010heteroarenes further reveal that the fusion of P\u2212Cp moiety leads to substantial intramolecular charge\u2010separated features with high ylidic character values of up to 84\u2009%. Benefitted from such dipolar structures, these P\u2010heteroarenes not only allows stepwise electrophilic substitution reaction for further structural \u03c0\u2010expansions, but also exhibit excellent nonlinear optical (NLO) responses and optical limiting (OL) performances comparable to or exceed those of C\n                    <jats:sub>60<\/jats:sub>\n                    .
