摘要

设计并合成了荧光素酰腙类衍生物对羟基苯基荧光素酰腙(FHP)

通过对荧光素的化学修饰

并采用酸碱以及二价铜离子为输入

实现了对由荧光素构成的二进制计算器加密的逻辑功能。该逻辑加密功能的实现是基于荧光素酰腙类衍生物对二价铜离子的特异性响应:在碱性环境中

二价铜离子催化FHP完全分解并释放出具有二进制计算器逻辑功能的荧光素分子;在酸性环境中

二价铜离子催化FHP部分分解并与二价铜离子配位形成稳定的二价铜离子配合物

该配合物既不能还原形成原化合物

也不能在碱性环境中释放出荧光素分子

导致该逻辑器件的逻辑功能被彻底破坏。基于该自毁装置的存在

使得该逻辑加密器件的安全性进一步提高。

Abstract

A fluorescein derivative named fluorescein hydrizido 4-imidophenol (FHP) has been designed to build a molecular logic device. The device is composed of two parts: lock-part and calculate-part. In this derivative

fluorescein is reffered to as calculate-part owing to it was previously adopted to mimic calculator. And the rest portion of this derivative is reffered to as lock-part. The operational principle of this device is that if input combination is optimal

calculate-part fluorescein is released and ready for calculating; if not

calculate-part remains locked. It effectively improves the security of calculator simulated by molecular logic. In addition

lock-part will be totally destroyed like self-distruction under a special input combination

resulting in that calculate-part can not be unlocked at all events. Hence

it is more sufficient to make brute-force attack on this device unrealistic.
