Solution Overview

Problem

Existing technologies fail to effectively resolve excited state energy in molecules, leading to detrimental reactions such as the formation of reactive oxygen species, which can cause damage to substances and organisms.

Innovation Solution

Conjugated fused polycyclic molecules, particularly those with electron-withdrawing groups, are used to quench and dissipate excited state energy by accepting electrons from chromophores, preventing the generation of reactive oxygen species and returning the molecules to their ground state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a molecule absorbs light energy, then the molecule transitions to an excited state, but this excited state can lead to detrimental reactions such as formation of reactive oxygen species

Engineering Contradiction:
Improvelight energy absorptionVSAvoidreactive oxygen species formation
Core Design Contradiction:
Use of energy by moving objectVSObject-generated harmful factors

Solution Approach 1:

The patent introduces a quencher molecule as an intermediary substance that mediates between the excited chromophore and oxygen. The quencher accepts energy from the excited chromophore through collisional energy transfer, preventing direct interaction between the excited chromophore and oxygen that would otherwise generate reactive oxygen species. This intermediary mechanism resolves the contradiction by providing a safe energy dissipation pathway.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent converts the harmful excited state energy that would lead to reactive oxygen species formation into a beneficial process by having the quencher molecule accept this energy and dissipate it harmlessly. The excited state energy, which is initially harmful, is transformed into thermal energy or other non-reactive forms through the quencher, thereby converting a harmful factor into a benign outcome.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Loss of energy

If existing technologies are used to resolve excited state energy, then some energy dissipation occurs, but the resolution is ineffective and detrimental reactions still occur

Engineering Contradiction:
Improveexcited state energy dissipationVSAvoideffectiveness of excited state resolution
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent optimizes key parameters of the quencher molecule including its energy levels, molecular structure, and concentration to maximize energy transfer efficiency. By carefully selecting the quencher's triplet state energy to be slightly lower than the chromophore's excited state energy, and by optimizing the quencher concentration, the system achieves reliable and effective excited state resolution that prevents detrimental reactions.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The quencher molecule serves as an effective intermediary that reliably transfers energy from excited chromophores. This intermediary mechanism ensures consistent and reliable energy dissipation, improving upon existing technologies that fail to effectively resolve excited states. The quencher's specific molecular properties enable reliable energy acceptance and dissipation, preventing reactive oxygen species formation.

Inventive Principle:
Principle #24Intermediary (Mediator)
