This Small Business Innovation Research (SBIR) Phase I proposal defines a new paradigm for 3D optical storage which relies on two-photon write and read mechanisms based on rapid, reversible proton photo-isomerization in asymmetric phthalocyanine molecules specifically designed to operate via a proton switching mechanism that eschews molecular motion and depends only on electron reorganization. This work will clearly delineate a new figure-of-merit that identifies molecular structures capable of enhanced optical memory characteristics. It is anticipated that such structure-property relationships will result in new ultra-fast terabit storage capabilities at least one order of magnitude better than the best contemporary materials. The operational temperature limit for these new materials is predicted to be in the range of electronic (Peltier) cooling to, at best, room temperature operation. This model will result in a radically new paradigm for an ultra-fast organic memory material, and a new benchmark for optical computing. Modern optical information storage (OIS) technology is shifting rapidly towards ultra-fast, multilayer, three-dimensional (3D) carriers of information. This technology could empower the average citizen with the capability of manipulating vast amounts of stored data, whether in text or visual format. Current technology cannot possibly meet this demand due to the inherentlimitations on memory based on nuclear motion.

这项小型企业创新研究(SBIR)第一阶段提案定义了3D光学存储的新范例，它依赖于基于不对称酞菁分子中快速、可逆的质子光异构化的双光子读写机制，该机制专门设计为通过质子切换机制来操作，该机制避免了分子运动，仅依赖电子重组。这项工作将清楚地描绘出一种新的品质因数，它可以识别能够增强光记忆特性的分子结构。预计这种结构-性能关系将导致新的超快太比特存储能力，至少比当代最好的材料好一个数量级。这些新材料的工作温度极限被预测在电子(珀尔蒂埃)冷却到最好的室温工作的范围内。这个模型将为超高速有机存储材料带来一个全新的范例，并为光学计算提供一个新的基准。现代光信息存储(OIS)技术正迅速向超高速、多层、三维(3D)信息载体转变。这项技术可以使普通公民能够处理海量存储的数据，无论是文本格式还是视觉格式。目前的技术不可能满足这一需求，因为基于核运动的存储器固有的局限性。
