Atomically Precise Molecules (APM)

The Defense Advanced Research Projects Agency (DARPA) Multi X Office is soliciting innovative proposals under solicitation DARPA-PS-26-141 for the Atomically Precise Molecules (APM) program. The objective is to develop new synthesis techniques for programmable precision polymers (PPPs) and nonlinear optical (NLO) materials to overcome performance gaps in optical communications and LiDAR. The program requires the development of scalable materials that culminate in a prototype demonstration integrated into a government-provided electro-optic modulator. Research focusing solely on inorganic materials or incremental improvements to the existing state of the art is specifically excluded. Awards will be issued as Other Transaction (OT) for Prototype Agreements under 10 U.S.C. § 4022. The performance period is milestone-based, featuring key deliverables such as an initial development plan, CMMC Level 2 operational compliance, and a final Phase II prototype demonstration by month 35. Proposals are evaluated based on technical approach, relevance to the DARPA mission, budget realism, and the capability to transition technology to military or industrial communities. Submissions must be made via the Broad Agency Announcement Tool (BAAT), with a final proposal deadline of December 18, 2026. Performers must adhere to strict cybersecurity requirements, including CMMC compliance and the protection of Controlled Unclassified Information (CUI).
