Metal\u2010organic frameworks (MOFs) or porous coordination polymers (PCPs), with their structural tunability and dynamic host\u2010guest chemistry, offer a powerful platform for engineering next\u2010generation ferroelectrics. However, progress in ferroelectric MOFs\/PCPs has been limited by their intrinsically weak polarization, restricting the realization of non\u2010trivial switchable ferroelectricity feasible at room temperature. We address this limitation, reporting a series of flexible PCPs with mixed donor\u2010acceptor (D\u2010A) stacks designed to achieve room\u2010temperature ferroelectricity\n                    <jats:italic>via<\/jats:italic>\n                    strong charge\u2010transfer interactions.

We furthermore show that the ferroelectric features of the PCP are closely related to the packing and geometry of the guest molecules incorporated.\n
